Strap for Annual Calendar Regulator 5235 White Gold / Silver

The Patek Philippe Complications 5235G-001 features a lug width of 20mm, which is the precise distance between the case lugs where the strap is secured via spring bars. This dimension requires extremely tight tolerances to ensure the strap adheres correctly without gaps or excessive play.

Alligator is the ideal choice for this Complications, thanks to its characteristic geometric grain and extraordinary durability that pairs naturally with the white gold case. Shell cordovan is an excellent alternative, developing a visibly improved patina over time. Vegetable-tanned calf offers comfort on the wrist, whilst rubber and NATO straps provide quick-change convenience through deployante clasps.

To change the strap, you must remove the spring bars connecting the strap to the case lugs. A dedicated spring bar tool allows extraction without damaging the case. If your strap features a deployante with double-shoulder closure, simply open the clasp to complete the operation. We recommend having a qualified watchmaker assist you the first time.

Yes, any strap with a 20mm lug width is compatible with the 5235G-001, provided the width is measured precisely (lug to lug, transversely). Artisanal straps from Casati Milano, available in all standard sizes, guarantee superior construction quality compared to generic solutions and allow customisation of leather and clasp.

The lifespan of a leather strap depends on the material chosen. Alligator and shell cordovan guarantee 5-8 years of daily wear, thanks to their dense fibrous structure. Vegetable-tanned calf typically lasts 2-4 years, requiring more frequent maintenance. Casati Milano straps with 18-month warranty cover any manufacturing defects during this period, but natural wear remains a physiological aspect of the garment.
